7.16 Input Mixer Registers, Channels 1–8 (0x41–0x48)
Input mixers 1, 2, 3, 4, 5, 6, 7, and 8 are mapped into registers 0x41, 0x42, 0x43, 0x44, 0x45, 0x46, 0x47,
and 0x48, respectively.
Each gain coefficient is in 28-bit (5.23) format so 0x80 0000 is a gain of 1. Each gain coefficient is written
as a 32-bit word with the upper four bits not used. For 8-gain coefficients, the total is 32 bytes.
Bold indicates the one channel that is passed through the mixer.
